A baseball player, with a great work ethic, and love for the game. Usually one of the better players, not because of natural talent, but because he works his ass off to be better at what he loves. Much more down to earth than any laxer he actually knows how to be a team player, and doesn't spend all his time bragging about which chicks he did the night before. Classy guy. Dustin Pedroia is a perfect example of a ballplayer. Bryce Harper is the anti-ballplayer.

Dustin Pedroia is a ballplayer!
Dude 1: Damn, did you see how hard he hustled to make that play?
Dude 2: Ballplayer.
